范文6“Get up, boy, it is time to go to school.”“I dislike having get up early. I can take an on-line lesson at anytime I like.”It is a completely ordinary dialogue occurring in modern life. Yes, it is the computer, whose ever-accelerated updating brings about tremendous changes in our school lives. A typical application is Computer Assisted Instruction (CAI), which aids teacher to impart knowledge to student more efficiently by it’s multimedia ch aracters. However, a vigorous debate over the issue whether or not teacher are byno means important in pedagogy field has intrigued the public. In my submission,the computer can be great help of teacher but they can never replace or surpassthe position of teacher. I will offer the following reasons.Firstly, CAI are designed ///http:/ /////and programmed by human instructor. They only condenseparts of teacher’s experience and intelligence. Moreover, being a successful instructor requires not just these factors but a wealth of experience and interpretnew experiences using that information. The computer after all are man-made machine.Secondly, the progress of instruction is complicated and complex, and the educational achievement of CAI is limited. Some sorts of course, such as basic educational course( 想想什么课程用电脑教不好), are not necessarily to be expressed by thecomputer to reach productive effect.Finally, communications and interactions with teacher and computer are quite different. The latter is too impersonal, which ruins the pleasure of emotional exchanges. Sometimes gazing at the cold flickering screen is a disinteresting and tiring experience.Admittedly, though computer may help teacher to provide student with a richer andmore effective learning environment, yet they can not substitute the position ofteacher, not only today, but the future.范文7Computer, as the most powerful tool in 21 century, is widely used in education areas. Whethe r computers can instead of teachers become a controversial issue. From my point, I don’t th ink computers can take the place of teachers.First and foremost, computer cannot communicate with students. Every human being has feelin g. Teachers are not only teaching students knowledge but also showing their loves to students when they are teaching. How to have a conversation with others and how to take care of oth ers can be learned from teachers. For example, teacher can take you to the hospital when yo u are sick. In comparison, computers cannot likely to it.Secondly, computers cannot help students when the get confused. Asking teachers is the best way to do when students get any quires. However, computers do not have this function. Stud y is a two-way process, teachers can excite students’ imaginations and fire their creation s.Last but not least, computers cannot organize teaching activities instead of teachers. Take England as an example, students need to do a lot of practical experiments, especially in p hysics and chemistry. When they do these experiments, students usually work together as a gr oup and discuss with teachers. Team work is a very important part to shape students’ person alities.From what has been discussed above, we might safely say that computers can never take the pl ace of teachers. We should always remember that human beings are the host of technology an d computer is a machine no matter how clever it is!(251 words)媛范文8V109 Computers “V” TeachersThe computer is widely used in education and some people think teachers are not playing an i mportant role in the classroom. To what extend do you agree or disagree?With more and more extensive use of computers in education, some people claim that the impor tance attached to teachers has been jeopardized. Therefore, computers will replace teachers in the classroom. However, it seems quite clear to me that learning from teachers is the m ost important way that cannot be substituted for students.Naturally, some people maintain that computer should instead of the old way of educatio n. They hold that the strong function of the computer offers a new mode of education, which is more interesting, more vivid and more acceptable by children. The students will not fac e to the serious teachers and calm classes any more, which are replaced by a brand-new worl d offered by the Internet. In addition, this can decrease the investment on the foundationa l education and save the human resources and material resources.As an assistant, computers do help teachers with their work, but they can never replace th e important role of a real teacher. The main functions of any computer are storage and calcu lation. It cannot think on its own anyway. All the teaching data stored in computers are th e essence of teaching experience generalized by many teachers during their work. Hence, to a ssist education, what a computer can do is just to repeat the contents summarized by real te achers.In addition, each student has different talents and different defects, and accordingly, the y may come across various problems during their study. Computer programmer designing the sof tware, however, cannot predict these problems. Therefore, a single computer can never solve these problems without a teacher’s guidanceFurthermore, if the significance of teacher has been weakened, the number of teachers may b e decreased, that is to say, many teachers may be laid-off. If such a case comes to realit y, series of social problems will break out, such as the drop of working opportunity which w ill surely make the burden of whole society become heavier and heavier.In conclusion, although computer-aided-education has spread widely, teachers still play s cr ucial part in the classroom, which cannot and will not be replaced by computer.范文9as the most important invention in the 21 century,computers have windspread in the world,an d the use of it has become the necessity of various spheres both in our work and in our dail y life. although computers are also greatly utilized in the education field,teachers are sti ll playing a crucial part on the platform. personally,i believe that teachers should not be replaced by computers due to the following reasons.being the architect of humanbeings' moral, teachers shoulder the responsibilities of passin g knowledge to students as well as shaping them to be real men with good qualities. student s may learn some certain knowledge from computers which are cold and senseless, but good qua lities can only be taught by teachers.at the same time,computers might not give detailed and understandable elaboration of complic ated theories. after judging whether the answers are right or wrong computers fail to tell t hem why they make such mistakes. the problems can only be dealt with by teachers.in addition,some elementary academic exchanges,such as discussion and association,cannot be organised by computers.nevertheless, teachers make up the deficiendy.by this means,studen ts' learning enthusiasm is greatly activated.above all,computers bring about many significant revolutions in the education field,but teac hers are still the hosts of the classroom.we should always bear in mind that men are the own er of technology and no matter how intelligent the computers are,they are merely man-made ma chines.。
